1. VDDQ = VDD = 2.5V ± 0.2V (minimum range to maximum range), f = 100MHz, TA = 25°C, VODC = VDDQ/2, VOPeak -Peak = 0.2V.
2. Although DM is an input-only pin, the input capacitance of this pin must model the input capacitance of the DQ and DQS pins. This is
required to match input propagation times of DQ, DQS and DM in the system.

1. Inputs are not recognized as valid until VREF stabilizes.
2. VREF is expected to be equal to 0.5 VDDQ of the transmitting device, and to track variations in the DC level of the same. Peak-to-peak
noise on VREF may not exceed ± 2% of the DC value.
3. VTT is not applied directly to the device. VTT is a system supply for signal termination resistors, is expected to be set equal to VREF, and
must track variations in the DC level of VREF.
4. VID is the magnitude of the difference between the input level on CK and the input level on CK
5. The ratio of the pullup current to the pulldown current is specified for the same temperature and voltage, over the entire tempera-ture and
voltage range, for device drain to source voltages for 0.25 volts to 1.0 volts. For a given output, it represents the maximum difference
between pullup and pulldown drivers due to process variation.
